BMS 250 Chapter Notes - Chapter 2: Hexose, Polysaccharide, Pentose
Document Summary
Acid, a common component of plasma membranes. Four classes of eicosanoids are produced and include prostaglandins, prostacyclins, thromboxanes, and leukotrienes. These molecules act locally and are signalling molecules associated with all body systems: they have primary functions in the inflammatory response of the immune system and communication within the nervous system. Other lipids: glycolipids- lipid molecules with carbohydrate attached- are also lipids. These molecules are associated with plasma membranes and serve several roles, including cellular binding to form tissues. Fat soluble vitamins such as vitamin a, e, and k are also lipids. Carbohydrate: meaning hydrated carbon , nearly every carbon is hydrated with the equivalent of a water molecule- that is, both an -h and an -oh are usually attached to every carbon. The number of carbon atoms typically ranges from 2-7, the least complex carbohydrates are simple sugar monomers called monosaccharides. All monosaccharides have between three and seven carbon atoms.
